Can a website owner use free tools to test their website's vulnerability to DDoS attacks?

While there are tools that claim to test DDoS vulnerabilities, using them on your own website without explicit permission or proper understanding can be risky and may even be misinterpreted as an actual attack. It's safer to consult with cybersecurity professionals who can conduct controlled penetration tests using ethical methods and specialized tools to assess your site's resilience without causing disruption.
